Overview ¶

Package aecache implements layers of caching for App Engine.

It provides 2 layers of caching:

process memory
cloud datastore

And combines them to provide a layered cache, fastest to slowest.

It only caches bytes, on top of which you can use encodings (json, gob, etc). Faster cache layers are refilled automatically from lower ones when hit. Values expires strictly after provided expiration.
